Enable remote access to IIS Express for debugging in Visual Studio 2013

In Visual Studio 2013 you can run or debug a project just clicking to the play button. But by default the project is reachable just from localhost and not reachable from any computer, phone or other device in local network. This is annoying when you want to test and debug using a mobile device. Here I show how to configure the environment to enable remote access to a local website running from VS2013.
